HOW NOISE-CANCELING HEADSET WORK

 Wired headset with noise cancelling microphone are a kind of headsets that reduce noise through a certain method. The current noise-cancelling headsets with mic are divided into two noise-cancelling modes: passive noise cancelling and active noise cancelling.

 

Wired Headset With Passive Noise Cancelling Microphone

 

Passive noise cancelling is an outdated method of noise cancelling. The reason why passive noise-cancelling is used is that it does not rely on the support of technology, thus reducing costs.

 

Wrapped to form a closed space: Passive noise-cancelling headsets mainly form a closed space by wrapping the ears and using sound-insulating materials such as silicone earplugs to block external noise. Without the aid of technology, the headset for noisy office can only block high-frequency noise, but can't do anything about low-frequency noise.

 

Generally, passive noise-cancelling headphones are headsets, and they are huge in size. For those who want to reduce noise in summer, passive noise cancelling is a very unwise way.

 

Active noise cancelling: wired noise-cancelling headset

 

The prerequisite principle of business headset noise cancelling is the interference principle of waves, which neutralizes the noise through positive and negative sound waves, so as to achieve the noise-cancelling effect. When two wave crests or wave troughs meet, the displacements of the two waves will be superimposed on each other, and the vibration amplitude will also be added. When in the peak and valley, the vibration amplitude of the superposition state will be cancelled. ADDASOUND wired noise cancelling headset has applied the active noise cancelling technology.
